using System;

class Test {

static float findArea(int a, int b, int c)

{

if (a < 0 || b < 0 || c <0 ||

(a + b <= c) || a + c <=b ||

b + c <=a)

{

Console.Write("Not a valid triangle");

System.Environment.Exit(0);

}

int s = (a + b + c) / 2;

return (float)Math.Sqrt(s * (s - a) *

(s - b) * (s - c));

}

public static void Main()

{

int a = 3;

int b = 4;

int c = 5;

Console.Write("The area is " + findArea(a, b, c));

}

Output:

The area is 6
